Last week, the Cybersecurity and Infrastructure Security Agency (CISA) published a “CISA Insights” report, highlighting increased cyber threats to critical manufacturing sector control systems due to the Covid-19 pandemic. The report points to three operational vulnerabilities that have arisen due to pandemic working conditions: (1) expanded cyber-attack surfaces (i.e. increased use of robotics and remote processes); (2) a lack of qualified personnel to protect highly technical manufacturing systems; and, (3) unauthorized access (both physical and virtual). As the report explains, ransomware “has begun to target systems lacking the inherent security controls required to protect themselves. The result can be catastrophic production loss and downtime as well as lost revenues and penalties for production delays.” CISA recommends that manufacturers develop cybersecurity and operational knowledge within the shop floor environment and invest in training for security analysts to be capable of remote monitoring of manufacturing environments.
